All slings, lightweight and heavy weight are constructed in the same way and have a lifespan of five years.”Ĭortland’s success with the prototype led to the development and commission of 270 kits in total to serve the Army’s fleet of helicopters and to be used in training.įor more information about Kaman Helicopters, contact John Navan, BCE & Subcontracts BD Manager. Unit Maintenance Aerial Recovery Kit (UMARK)( Book ). The kit consisted of an assortment of lightweight lifting members, slings, lines, metal fitting and elastomeric components, which allow rigging and recovery of a wide array of U.S Army helicopters.ĭoug Bentley, Sales Engineer for Cortland, said: “The biggest challenge that faced us was creating the hand-braided slings which were tricky as we had to develop them through a handicraft process. Cortland’s new solution brought the kit weight down to less than 100lbs.Īfter submitting its proposal, Cortland was tasked with a small development project, from which an early prototype kit was created. The Army’s existing recovery kit was made from polyester and weighed several hundred pounds. Testing and tension cycling proved strength levels that surprised both Kaman and those commissioning the project from the army.Īs with the tethered hover, the main test facing the team delivering the UMARK was lift capacity, flexibility, yet meeting the desired small diameter of the load pins for reduced weight reduction. It also needed to be simple enough for it to be deployed by minimal personnel.Ĭortland’s reputation for designing and building project-specific high strength fiber solutions ensured the company was Kaman Aerospace’s first port of call for the job.Ĭortland had previously designed and built a tethered hover for the Naval Air Test Center (NATC), a vital piece of equipment used for studying downwash from a helicopter therefore understood Kaman’s needs and challenges when it came to the need for lightweight, high specific strength rope yet flexible enough to be stored in a small space.Ĭortland delivered a new kit with 27 parts in total including 3 pendants. However the kit needed to be smaller and lighter to free-up lift capacity for other cargo. The UMARK equipment, like its predecessor ARK, is used to provide aerial recovery capability for Army helicopters. military project to design and build a Unit Maintenance Aerial Recovery Kit (UMARK) to replace the U.S Army’s aging Aerial Recovery Kit (ARK). The FCRS-60-AA is backward-compatible with legacy and discontinued products provided by other. Together, they comprise a complete solution for rigging the H-60 flight controls in a fast, safe, and predictable manner. Cortland was approached by Kaman Aerospace who had been presented with a new U.S. The Flight Controls Rigging System (FCRS-60-AA) for H-60 by EAA Tools is a two-part kit, including a full pin set (FCRK-60-AA) as well as an accessories kit (FCRA-60-AA).
